` REEL FOR SACK-TYING lACI-IINES.

Application :tiled April 7, 1922. Serial No. 550,532.

To all whom t may concern. Y v

Be it known that I, GEORGE M. liAsnN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Reels for Sack-Tying Machines, of which the following is a specification.

This invention relates to improvements in reels for sack tying machines, and has for its object a structure on which is placeda coil of wire or other material, and placed in a convenient position relative to the feeding machine of a sack tying machine; the said reel being so constructed as to revolve slowly as the wire is being fed through the tying machine.

A further object of my invention is to construct a reel consisting preferably of a statt` on which is revolubly mounted a coil supporting frame on which the coil of wire or other material is supported and the same so arranged as to provide free movement during the unwinding of the coil and to provide for the tension and slaclr, at the same time preventing the'wire from kinking or twistino' during the iin-winding process.

Iigure 1, is a Vertical central sectional view of my improved reel.

Fig. 2, is a top plan view of the same.

Fig. 8, is a detail sectional view of the upper bearing made use of.

Fig. 4, is a perspective view of my invention.

In the general construction of my invention I provide a reel consisting of a base or foot section 5, on whichis firmly supported a staff 6. Over this staff is placed a coil supporting frame consisting ofa platform or table 7 provided with a central opening 8 which is of a diameter somewhat larger than the staff 6. l

On the periphery of the platform or table 7 and at suitable intervals apart I provide arms 9, and on the top of the arms is attached a rail or band 10.

On the tableand at suitable intervals apart I provide a'plurality of standards 11, which are inclined and the upper ends are attached to a top 11', thus the uppei' end of the extension is of smaller diameter than the base or the bottom, where the standards are attached to the platform.

On the under side of the top 11', I provide a socket bearing 12, in this bearing is placed a bearing ball 13 which is seated in a depression 14 formed in the socket, and a depression lformed inthe top of the staff; thus the entire weight of the coil supporting frame is suspended on the top of the staff and'rby means of the bearing ball a great portion of the friction is eliminated.

@n the bottom of the platform I place a bearing plate or disc 16 which is provided with acentral opening 17 of a size sufliciently large'to fit around the periphery of the sta' and act as a semi-frictional bearing.

This structure of a reel is used in conjunction with a sack tying machine and on the platform between the standards 11 and the arms 9 is placed the coil of wire as that indicated b y dotted lines inFig. 4. Y

The end of the wire is fed into the bearing mechanism of the tying machineand durin the operation, as the wire is fed through the machine the pulling effect on the wire causes a slow revolving action on the reel and while the wire is beingV unwound it has a tendency to rise upwardly on the inclined body as that shown by dotted lines in Fig. 4, and during this un-winding action the reel is permitted to revolve slowly and allows for the spreading of thel wire in the event of sudden stoppage and too much play or sag. It 'likewise permits the wire to un-wind evenly and prevents kinlring and twisting, and by means of the arms 9 and rail 10, it likewise keeps the wire within that section of the reel even, in the event the reel should operate a little more in advance of the feeding of the wire in the machine. l

The reel is placed in any convenient location to the feeding mechanism of the tying machine.

Having fully described my invention what I claim is:

.1. A reel used in conjunction with sack tying machines comprising a platform, a rail carried thereby, a plurality of standards mounted on the platform and extending upwardly; a top secured to the upper ends of the standards, said top being of smaller diameter than the base, a ball journal supported under the top; a standard projecting into the journal and on which the reel is revolubly mounted; a bearing plate supported on the bottom of the platform and in loose communication with the periphery of the staff, and the base on which the standard js drigidly mounted, substantially as speci- 2. A reel used in conjunction with sack tying machines, comprising a circular plating plate 16 located on the bottom of the platform and surrounding the Shaft 6, substantally as specified.

in testimony whereof, I have Signed my 15 name to this specification, in presence of two subscribing Witnesses.
